Ten new isoprenoids have been isolated from two marine sponges Ptilocaulis spiculifer and Axinella weltneri. P. spiculifer afforded three triterpenes, dihydroyardenone (1), abudinol B (2), muzitone (3) and two Ct3 and CI7 metabolites of abudinol, nakorone (4) and durgarnone (5). A. weltneri gave fiv
New cytotoxic compounds l-7 were isolated along with onnamide A (9) from a marine sponge Theonellu sp. collected at Hachijo Island, whereas another Theonelka sponge yielded 8. The structures of these compounds were determined by interpretation of the NMR spectral data as well as by comparison of spe
